A Quick Overlook about the Traits of the Shot Blasting Rubber Sheet!

But what exactly is a shot blasting process?

In order to understand the significance of a shot blasting rubber sheet, you will first need to grasp the ins and outs of a shot blasting process; and it goes something like this –

Shot blasting or abrasive blasting is the process of propelling a stream of highly abrasive particle at extreme speeds and under extreme pressure against a surface in order to either roughen it or to make it smooth.

Not only that, but the process is also used to give a surface a proper shape, and also for removing any trace of contaminants.

A pressurized fluid preferably compressed air or a centrifugal wheel is what is used to propel the media or the blasting material towards the surface.

(Bonus info: Benjamin Chew Tilghman was the first person in history to use the abrasive blasting process way back on the 18th of October 1870).

The difference between the two main types of abrasion blasting process – Shot blasting and Sandblasting –

While considering the various types of the abrasion resistance process, there are many different types.

However, there are two variants that are considered by many as highly abrasive. And they are Shot blasting (which uses metal shots) and Sandblasting process (which uses sand particles), with the primary difference being in the type of media being used.

Hence, let us sneak a peek at some of the other differences between the two:

 While sand needs no special introduction, a proper explanation regarding what shot means needs to be given.

A shot is nothing else but the pure metal balls, which may or may not be of a triangular shape, and are made of pure steel.

Hence, while discussing the difference between the two, it needs to be said that sand particles offer unmatched cleanliness over rust and other forms of corrosion.

 And because shots are metallic themselves, it provides the requisite profile depth and dent on the metal on which the blasting process is applied.

Yet another important difference between the two is the area in which the two processes can be performed.

 According to experts, the Shot blasting process must be performed in a closed and surrounded area as the metallic particles used in the blasting process can cause fatal injuries.

However, a Sandblasting process can be easily performed in an open area as the chances of causing fatal injuries are significantly lower than that of the Shot blasting process.

Are these the only two types of media used in the blasting process?

 Of course not!

 In fact, the sheer idea that existed in the 1900s where people considered sharp grains to be more useful has been long since been proven wrong.


 Silica is probably the most commonly used mineral abrasive used in the blasting process.

But since it breaks up easily to create larger quantities of dust, the operator might develop lung disease, one of the main reasons why it is coated with resins which are responsible for controlling the dust.


 These constitute of soft abrasives like fruit kernels or crushed nut shells which are used as they prevent the underlying material from getting damaged, like while you are cleaning a brick or removing graffiti.


 Very much like the agricultural ones, these soft abrasives which include dry ice, wheat starch, sodium bicarbonate, etc. these are used for cleaning and removing coatings from printed circuit boards.

Some of the safety equipment used by operators:

      Positive pressure blast hood

 It has a head suspension system which enables the head to move with the device. In addition to this, it also has an air-feed hose.

      Self-contained oil-less air pump

 It protects the operators from the harmful and sometimes fatal effects of the harmful gases, and hence it has an air filtration and carbon monoxide alarm.

      Rubber sheets for personnel protection

 A shot blasting sheet which is made from a unique blend of synthetic and natural rubber sheet  is probably the most widely used protective gear that is also preferred by the operators.
